Quality and guarantees

1Do the certificates of analysis come from an independent laboratory?

Yes. 26 lots are analysed by Amino Metrics, a third-party laboratory. Each certificate shows the lot number, the analysis date and a verification code to enter on the laboratory’s website.

• Lot number (format AM-YYMM-NNNN), date received and date tested on every certificate.
• Verification code shown on every lot page: entered on aminometrics.com/verify, it brings up the original certificate from Amino Metrics.
• The original PDF is published unchanged on each lot page.

2Which analyses appear on the certificates?

A purity analysis by HPLC (99.02% to 99.95% on published lots) and an assay of the net content of each vial. Retention time is compared with a reference standard.

• HPLC purity, pass threshold 99% on the published certificates.
• Net content per vial, measured by absorbance (Beer-Lambert law), tolerance 90 to 115% of the stated amount.
• Retention time compared with a reference standard. The laboratory states that this match is not formal proof of identity.
• Mass spectrometry: not yet included in our certificates.

3Are endotoxins and microbiological contamination tested?

Not at this time. Our certificates cover purity and net content. They do not cover endotoxins (LAL), sterility or microbial load. Products are sold for laboratory research, not for human or veterinary use.

• No endotoxin or sterility result is published, so the site does not claim one anywhere.
• You can have a vial tested by the laboratory of your choice; a non-compliant result is covered by the guarantee below.

4What are the shipping and refund conditions?

Delivery within 15 days with a tracking number, to 34 European countries, in a plain parcel. A parcel seized by customs is replaced or refunded on proof, and a lot below 98% purity or 90% fill is replaced or refunded on a certificate from an independent laboratory.

• Shipping: €39 below €300, €19 from €300, free from €500.
• Online order tracking with the order number and the email used.
• Customs seizure: replacement or refund on a seizure notice or official notification.
• Purity below 98% or fill below 90%: replacement or refund on a certificate from an independent certified laboratory.
• Not covered: poor storage, use outside research, incorrect handling after delivery.
